Description
Technical field
The invention belongs to burning and equip field with heat supply process, be specifically related to fuel and revolve floating burning and medium heat conduction technical equipment, particularly a kind of liquid medium heat conducting furnace revolving floating burning.
Background technology
As prior art, the combustion apparatus kind of the thick dusty fuels such as burning rough coal powder, rice husk is more, as single flow, eddy current type, reverse-flow type etc.When these coal dust furnaces are less than the coal dust of 50 μm for particle diameter, efficiency of combustion is high, and in ash, phosphorus content is less than 1%.When the particle diameter that burns is greater than the rough coal powder of 50 μm, due to the finite volume of burner hearth, fuel is shorter for the burning time in burner hearth, and coal dust likely burns endless, and likely from the combustion gas of burning, is deposited to the bottom of burner hearth, reduces efficiency of combustion.And the coal dust that particle diameter is less than 50 μm need be equipped with special disintegrating apparatus, as Raymond mill.In addition, the particle diameter of coal charge is thinner, preserve difficulty and expense also larger.
The combustion furnace kind of combusting rice hull is also more, as swinging, oscillatory type, reciprocating, fixed-bed type, fire grate and suspension combustion convolution etc.For the biomass fuel of the similar rice husk particle size of particle diameter, there is fire grate combustion system as adopted, then because fire grate is in the complex environment of high temperature, many ashes, make combustion furnace structure complexity and maintaining difficulty.According to without fire grate combustion system, then the particle diameter because of biomass fuels such as rice husks is comparatively large, likely settles down from combustion gas, efficiency of combustion is reduced.

In addition, the suspension combustion mode of current fuel in burner hearth is also more, make to be in suspended state during fuel combustion, the air-flow rate of climb must be made to be greater than the floating velocity of fuel.And when the differing greatly of the particle diameter of fuel and severe, all fuel be allowed all to be in suspended state, and extend the burning time of fuel as far as possible, truly have sizable difficulty.Because the floating velocity of the fuel that particle diameter is little is little, be easily accelerated, the combustion intermittence in burner hearth.And the floating velocity of the larger fuel of particle diameter is comparatively large, not easily suspend.If make the fuel of greater particle size be in suspended state completely, then make air quantity be multiplied, concentration will be caused too low, furnace temperature is declined, serious situation will make continuous burning difficulty.
